Overview
Tomboy describes a girl — or, less often, an adult woman — whose dress, play, interests and manner run to what a given society codes as masculine. It is the oldest word in this part of the vertical by several centuries, and the most common: for most of the people it has been applied to, it named a phase of childhood rather than a permanent identity.
Two things distinguish it from the other expression terms here. It is applied to children, mostly by adults, before the child has any say in the matter; and it is not, in most usage, an LGBTQ+ term at all. Tomboyism does not predict adult sexual orientation and does not indicate a transgender identity, though a minority of the people described by it turn out to be one, the other or both.
Definition & scope
The content of the word is entirely relative to the society applying it. What counts as tomboyish — trousers, team sport, rough play, a preference for boys as playmates — is a list of things a particular culture has assigned to boys, and the word changes as the list does. That makes tomboy a clean example of gender expression: it describes the distance between a child's behaviour and a local expectation, and says nothing about who that child is.
The label sits alongside butch and gender nonconformity but is not a synonym for either. Butch is an adult self-description within lesbian and queer women's communities; tomboy is usually applied from outside and usually to a child. The nearest masculine-side counterpart is the modern coinage femboy, and the difference in their receptions — tomboy affectionate and long-established, femboy contested and new — is one of the sharper asymmetries in this vocabulary.
History & origins
- 1530s–1550s: tomboy is first recorded, meaning a rude or boisterous boy. Dictionaries differ on the first attestation, with the Oxford Dictionary of English giving 1533 and Etymonline the 1550s.
- 1570s: the sense shifts to a bold or immodest woman — for a period the word was an insult about sexual forwardness, not about play.
- 1590s–1600s: the modern sense settles: a wild, romping girl who behaves like a spirited boy.
- Late nineteenth century: American health reformers reverse the valuation, arguing that vigorous outdoor girlhood produces healthier women; surveys of the period record Charlotte Perkins Gilman praising tomboyism's benefits in Women and Economics (1898) and the playground advocate Joseph Lee describing a tomboy phase in 1915 as necessary to girls' development.
- 1977: the first serious prevalence measurement is published, and finds the behaviour to be a majority experience rather than a deviation.
- 2002: the Tomboy Project begins recruiting and studying tomboys directly rather than inferring them from adult recollection.
In practice
Because the label is applied by others, its practical significance is mostly about tolerance. Tomboyism has historically been permitted — indulged, even — in a way that feminine behaviour in boys has not, and that asymmetry is consistent across the research: the same society that finds a girl in a football kit charming finds a boy in a dress alarming. The permission is also time-limited. It is conventionally withdrawn at adolescence, when the girl is expected to stop, and much of the qualitative literature on tomboyhood is about that withdrawal rather than about the behaviour itself.
Psychology
Tomboyism is not a disorder and has never been one. The ICD-11 removed gender incongruence from its mental-disorders chapter in 2019, and ordinary childhood gender nonconformity has no diagnostic status of its own.
The empirical picture is straightforward. Bailey, Bechtold and Berenbaum's study in Archives of Sexual Behavior recruited 60 tomboys aged 4 to 9 and compared them with 15 sisters and 20 brothers on playmate preference, sex-typed activities and gender identity. On nearly every measure the tomboys were substantially more masculine than their sisters and generally less masculine than their brothers — that is, they occupied an intermediate position rather than crossing over. The paper's framing throughout is the one its opening sentence states: tomboys are girls who behave like boys, which makes the label a fact about interests, playmates and activities rather than a claim about being a boy.
Prevalence & culture
How common is being a tomboy?
Common enough that the research literature has repeatedly had to argue against treating it as rare.
The foundational measurement is Hyde, Rosenberg and Behrman's 1977 study in Psychology of Women Quarterly. Prompted by an initial observation that 78% of a group of undergraduate women recalled having been tomboys, they found 63% of junior-high girls reporting themselves tomboys and 51% of adult women reporting having been one in childhood. Their conclusion was that tomboyism is statistically quite common with little indication of anything abnormal about it.
Later self-report data agrees on the shape. In the National LGBTQ+ Women's Community Survey, tomboy was the second most common past gender descriptor among the 2,048 respondents who elaborated, chosen by 30%, but only 14% used it currently — the clearest available demonstration that the word names a stage most people leave.
| Source | Population | Finding |
|---|---|---|
| Hyde, Rosenberg & Behrman (1977) | junior-high girls and adult women | 63% of girls; 51% of women recalled childhood tomboyism |
| Bailey, Bechtold & Berenbaum (2002) | 60 tomboys aged 4–9 vs siblings | more masculine than sisters, less masculine than brothers |
| LGBTQ+ Women's Community Survey | 2,048 elaborating respondents | 30% past descriptor, 14% current |
Because the term is applied overwhelmingly to girls and women, any population figure has to be halved on the way out, and the figure recorded on this entry does that explicitly.
Common questions
What does Tomboy mean?
A girl or woman whose dress, play and interests run to what a given society codes as masculine. Tomboy is a description of expression rather than identity, it is usually a phase rather than a permanent label, and it is statistically ordinary rather than rare.
What else is Tomboy called?
Tomboy is also known as tom, tomboyish and tomboyism.
- ButchA masculine gender presentation and self-description used chiefly by lesbian and queer women. Butch names how a person carries gender rather than which gender they are — most butches identify as women — and it took its modern form in working-class lesbian bar culture in the 1940s.
- FemboyAn internet-native term for a young man or masculine-assigned person who presents in a conventionally feminine way. It describes expression, not identity or orientation, and it is not a sexual interest — a distinction the word's history online makes necessary to state.
- Gender NonconformingAn umbrella description for people whose gender expression departs from what their society expects of their sex or gender. It describes presentation rather than identity: a cisgender man can be gender nonconforming, and a transgender woman may not be.
- WomanOne of the two binary genders: a person whose gender is woman. The category includes cisgender and transgender women alike, and it is distinct from “female”, which in careful usage refers to sex characteristics rather than to gender.
A compound of the name Tom — used generically for an ordinary man, as in tomcat — with boy. First recorded in the sixteenth century meaning a rude or boisterous boy (1533 by the Oxford Dictionary of English, the 1550s by Etymonline), it shifted in the 1570s to mean a bold or immodest woman, and by the 1590s had settled into its modern sense of a girl who behaves like a spirited boy. The obsolete tomrig was a close synonym. The word is one of very few gender terms whose referent changed sex entirely within a century of its coinage.

Basis: DERIVED, not measured: Hyde, Rosenberg and Behrman (1977, Psychology of Women Quarterly) found 51% of adult women reporting they had been tomboys in childhood and 63% of junior-high girls describing themselves so. Applying the adult-recall figure to the female share of the world population, which the World Bank puts at 49.7% for 2024, gives roughly a quarter of all people having been described this way at some point. The figure is retrospective and lifetime rather than current — the same survey tradition finds far fewer people using the word of themselves as adults — and the underlying study is nearly fifty years old.
